SUPERHEATED  STEAM  AS  A  ttORKING  FLUID 


Dr.  Iiobert  Henry  Thurston  In  his  work,  MA  Manual  of 

t)y"i>.;t-lC  ."'  t  firmly  0.  i\\.i  •'.'••  >  •: 

the  Steam  Engine, w  has  given  expression  to  the  ideas  of  the 
highest  authorities  of  the  day,  with  regard  to  the  working 
qualities  of  superheated  steam.   His  introductory  state- 
ments to  the  subject  are  as  follows: 

"superheated  Steam  *  «  •  •  •  can  probable  never  be  used 
in  the  ordinary  steam  engine,  and  even  superheating , in  its 
legitimate  function  of  reducing  liability  to  interior 
\7astes,  is  employed  comparatively  infrequently.   It  is  not 

used  as  a  working  substance  for  the,  reason  that,  in  order 

Deri  od 
that  it  nay  rofcain  the  gaseous  state  throughout  tho  expansionA 

it  must  be  superheated  initially  to  a  higher  temperature 
than  is  found  ordinarily  safe  or  practicable;  or,  otherwise, 
a  ^ray,  as  yet  undiscovered,  r,iust  be  found  to  so  aodify  the 
engine  itself  as  to  pernit  its  safe  use,  and  at  the  same 
time  to  prevent  those  wastes  of  heat  which  now  so  promptly 
convert  the  steam,  at  entrance,  fron  the  superheated  to  the 
saturated  or  wet  condition*1* 

The  above  statement  is  hov?ever  qualified  by  this; 
"Could  it  be  employed, its  characteristics  would  be  those  of

the  gases,  .....  It  would  Insure  a  high  theriaodynami  c 
efficiency,  combined  with  the  high  mechanical  efficiency  of 
the  steam  engine." 

In  "a  steam  engine  using  superheated  steam  .'i^v., 
the  condensation  at  entrance  is  reduced  in  amount;  but, 
ordinarily,  at  least,  the  fluid  is  still  more  or  less  wet 
at  the  point  of  cut-off.   Superheating  is  thus,  as  commonly 
practiced,  simply  a  method  of  economizing  by  reduction  of 
interior  waste." 

"It  is  probably  never  the  fact,  in  practice, "that  it 
is  possible  to  secmre ,  safely  and  economically,  so  such 
superheating  as  is  needed  to  keep  the  steam  dry  throughout 
the  stroke." 

"i'he  superheating  of  the  'Lteara.  continually  improves  the 
working  of  the  engine  inT(l),  giving  a  better  working  sub- 
stance and  thus  initially  reducing  interior  wastes;  -  (2), 
at  the  same  time,  meeting  more  completely  the  demand  for 
heat  to  bring  up  the  temperature  of  the  metal  to  that  of 
the  prime  steam  before  the  entrance  of  the  latter  into  the 
cylinder,1* 

William  J.  M.  Hankine,  in  his  work  "Steam  Engine  and 
other  Prime  Hovers" ,  makes  the  following  statements  in  regard 
to  the  use  of  superheated  steam: 

"The  objects  and  methods  of  superheating  steam. 
(1),   To  raise  the  temperature  at  which  the  fluid  re- 
ceives heat,  and  so  as  to  increase  the  efficiency  of  the

fluid,  and  that  without  producing  a  dangerous  pressure. 

(£)•  £°  diminish  -he  density  of  the  steam  employed  to 
overcome  a  given  resistance,  and  so  as  to  lessen  the  back 
pressure, 

(3).  To  prevent  condensation  of  the  steam  during  its 
expansion  v/ithcut  the  aid  of  a  jacket. 

The  princinal  methods  of  superheating  are  the  following: 

(1)   Wire-drawing,  occasionir^  superheating  when  the 
pressure  in  the  cylinder  is  inch  less  than  that  in  the  boiler. 
Superheating  ......  takes  place  more  by  accident  than  design, 

and  does  n&t  secure  the  advantages  ascribed  to  It. 

(2).  Gy  the  ct can- jacket,  taking  place  v/hen  the  steam- 
jacket  coiimunicatos  more  heat  to  the  sylinder  steam  than  is 
necessary  merely  to  prevent  any  of  it  fron  condensing.   This 
kind  of  superheating  cannot  be  subject  tc  definite  calcula- 
tion, -  and  its  extent  is  limited. 

(3)   Superheating  in  the  steam  chest  or  tipper  part  cf 
the  boiler  by  means  of  flues  traversing  or  surrounding  it. 
By  this  method,  the  stea.n  may  be  raised  to  a  temperature 
somewhat,  but  not  very  ;;iu-u  exceeding  the  boiling  point 
corresponding  to  the  pressure  in  the  boiler. 

(4).   Superheating  in  tubes  or  passages  which  the  steam 
traverses  on  its  v/ay  fro.n  the  boiler  tc  the  cylinder.   By 
this  'method,  almost  any  required  temperature  can  be  given  to 
steam  of  any  pressure. 

(5).   Superheating  by  mixture, where  a  portion  only  of

tho  steam  is  passed  through  superheating  tubos,  and  raised 
to  a  very  high  temperature,  and  then  injected  amongst  the 
remainder  of  the  steam  at  or  near  the  cylinder  ports.
